FIG. 1 is a diagram for illustrating an outlineof the pair of contact lenses 100 according to an embodiment of thepresent disclosure. As shown in FIG. 1, the pair of contact lenses 100is a contact lens set including a contact lens 1R to be worn on a righteye 4R and a contact lens 1L to be worn on a left eye 4L.

Each of the contact lenses 1R and 1L, which is formed of a lens parthaving a curved surface shape, can be worn on an eyeball 4A so as tocover an iris 2 and a pupil 3 as a whole and can be taken off from theeyeball 4A. Note that, in the following description, the contact lenses1R and 1L will be collectively referred to as contact lenses 1, when itis not necessary to distinguish therebetween.

(Background)

As described above, there have recently been a growing number of userswho wear prescription contact lenses for vision correction as well ascolored contact lenses to change the appearance of eyes. In addition,improving the functionality of such daily use contact lenses has alsobeen proposed.

However, it has not been proposed to cause a pair of contact lenses wornon both eyes to operate in coordination with each other.

By taking into account these circumstances, highly-functional contactlenses according to embodiments of the present disclosure are created.According to each embodiment of the present disclosure, one of thecontact lenses operates in coordination with the other one of thecontact lenses that is worn on the other eye and that has a differentfunction, thus enabling to make the contact lenses intelligent and tosignificantly improve the convenience thereof.

Hereinafter, with reference to FIG. 2, specific description will begiven of a basic configuration of contact lenses according to each ofthe embodiments.

<1-1. Appearance Configuration>

FIG. 2 is a plane view showing an exemplary appearance configuration ofa contact lens 1 according to an embodiment of the present disclosure.As shown in FIG. 2, the contact lens 1 according to the embodiment isformed of a lens part 10 worn on an eyeball, and, as viewed from thefront of the eyeball, is divided by a circle 1C into a region 1A insidethe circle 1C and a region 1B outside the circle 1C. The circle 1C has adiameter D2 approximately equal to or larger than a diameter D1 which isthe maximum diameter of an inner circumferential circle 2A of the iris 2of a human eye.

In the region 1B outside the circle 1C, a circuit unit 20 is provided. Asmoothing part formed of a material such as a transparent syntheticresin is formed on an outer side (side opposite from a side having asurface, contacting the eyeball, of the lens part 10) of the circuitunit 20. This allows a user wearing the contact lenses 1 to smoothlymove his/her eyelids.

As shown in FIG. 2, the circuit unit 20 according to the embodimentincludes a control unit 21, a radio communication processing unit 22, anantenna 23 and a function unit 30. Hereinafter, description will begiven of these components.

(Control Unit 21)

The control unit 21, which is formed, for example, of a microcomputer(microchip or IC chip) including a central processing unit (CPU), readonly memory (ROM) and random access memory (RAM), controls thecomponents of the circuit unit 20.

Specifically, the control units 21 according to the embodiment controlthe function units 30 (a first function unit 30R and a second functionunit 30L) provided respectively to the pair of contact lenses 100 andhaving mutually different functions so that the function units 30 canoperate in coordination with each other.

(Radio Communication Processing Unit 22 and Antenna 23)

The antenna 23, which is provided, for example, at the outer peripheryof the region 1B of the lens part 10 as shown in FIG. 1, is connected byradio to the other one (example of an external device), worn on theother eye, of the contact lenses 1, and has a data transmission andreception function.

The radio communication processing unit 22 has a function of performingvarious kinds of signal processing on the data transmitted and receivedby the antenna 23.

(Function Unit 30)

The function unit 30 performs a predetermined function according tocontrol by the control unit 21. The function unit 30 performs at leastany of an imaging function, a display function, various sensor functions(including an UI function), an illumination function, a sound collectionfunction (may be used as an example of the UI function), a power supplyfunction and an external communication function, for example. Note thatthe placement, shown in FIG. 2, of the function unit 30 is only anexample. Alternatively, when, for example, the function unit 30 has adisplay function as the predetermined function, the function unit 30(display unit) having the display function is provided so as to coverthe region 1A, which is inside the circle 1C, of the lens part 10, sothat a wearer (user) recognizes an image displayed thereon. In addition,when the function unit 30 (display unit) having the display function isprovided so as to cover the region 1A, the circuit unit 20 is providedin the region 1B, which is a peripheral region outside the display unit26, so as not to hinder images displayed on the display unit.

The pair of contact lenses 100 (contact lenses 1R and 1L) according tothe embodiment respectively include the function units 30 (first andsecond function units 30R and 30L) having mutually different functionsand operate in coordination with each other through the radiocommunication processing units 22 and the antennas 23. Providing thefunction units 30 having mutually different functions respectively tothe pair of contact lenses 100 (contact lenses 1R and 1L) can make anarea for placing the function units 30 smaller than when both areprovided to one of the contact lenses 1.

Conceivable combinations of such different functions includecombinations of “an imaging function and adisplay/illumination/storage/battery/external communication/UIfunction,” “a display function and anillumination/storage/battery/external communication/UI function,” and “astorage function and a battery/external communication/UI function,” forexample. In addition, combinations of subdivided imaging functions suchas “a special imaging (zoom/infrared/ultraviolet imaging) function and anormal imaging function,” “a distant-view imaging function and anear-view imaging function” are also conceivable. As described above,there are various combinations of different functions, which are notparticularly limited. However, specific examples of coordinatedoperation of different functions performed by the pair of contact lenses100 according to each of the present embodiments will be described indetail in the next “2. Embodiments.”

Hereinabove, the basic appearance configuration of the contact lenses 1has been described. However, the configuration of the circuit unit 20according to the embodiment is not limited to the example shown in FIG.1, but may additionally have a battery (power supply unit). In addition,the antenna 23 and the radio communication processing unit 22 of thecircuit unit 20 may have a function of receiving power supply, and canreceive power supply from an external power supply device (not shown) bya method such, for example, as an electromagnetic induction method, anelectric wave method or an electromagnetic field resonance method.Moreover, in addition to being connected by radio to the other one, wornon the other eye, of the contact lenses 1, the radio communicationprocessing unit 22 and the antenna 23 according to the presentembodiments may also be connected by radio to an external communicationterminal (a smartphone or the like carried by the user, for example).Note that the arrangement of the components of the circuit unit 20 shownin FIG. 1 is only an example, and the configuration of the circuit unit20 according to this embodiment may be different from that shown in FIG.1.

Next, by using multiple embodiments, specific description will be givenof the coordinated operation of different functions performed by thepair of contact lenses 100.

«2. Embodiments»

<2-1. First Embodiment>

Firstly, with reference to FIGS. 3 to 4, description will be given ofcoordinated operation according to a first embodiment in which one ofthe contact lenses 1 has an imaging function, and in which the other oneof the contact lenses 1 has a display function.

(2-1-1. Configuration)

FIG. 3 is a block diagram showing a configuration of the pair of contactlenses 100 according to the first embodiment, which are formed of acontact lens 1L-1 to be worn on the left eye 4L and a contact lens 1R-1to be worn on the right eye 4R.

As shown in FIG. 3, the contact lens 1L-1 has a control unit 21L-1, theradio communication processing unit 22, the antenna 23 and a functionunit 30L-1. The function unit 30L-1 includes an imaging unit 24 and asensor 27.

(Imaging Unit 24)

The imaging unit 24 (camera) has a lens system, a drive system and asolid state image sensor array and the like. The lens system includes animaging lens, a diaphragm, a zoom lens, a focusing lens and the like.The drive system causes the lens system to perform a focusing operationand a zooming operation. The solid state image sensor arrayphotoelectrically converts imaging light acquired by the lens system togenerate imaging signals, and may be materialized, for example, with acharge coupled device (CCD) sensor array or a complementary metal oxidesemiconductor (CMOS) sensor array.

The imaging lens is provided so that the imaging direction thereof cancoincide with the eye-gaze direction of the user wearing the contactlenses 1.

In addition, the imaging unit 24 has an imaging signal processing unitconfigured to perform processing on signals acquired from the solidstate image sensors to acquire imaging signals as digital data. Forexample, the imaging signal processing unit may perform eye-shakecorrection for correcting blurring of an imaged image due to eyeballmovement. The imaging unit 24 outputs, to the control unit 21L-1, animaged image (digital data) thus acquired.

(Sensor 27)

The sensor 27 is any of various sensors for sensing information on anoutside world (surrounding environment) around the contact lenses 1, andis materialized with a sensor such, for example, as a piezoelectricsensor (example of a pressure sensor), an infrared sensor or anacceleration sensor. The sensor 27 according to this embodiment is usedfor detecting a camera activation command, an imaging command and acamera end command. The sensor 27 outputs a sensing result to thecontrol unit 21L-1.

(Control Unit 21L-1)

The control unit 21L-1 detects various commands based on sensing resultsby the sensor 27, and controls the components of the contact lens 1L-1in accordance with the various commands thus detected. In addition, thecontrol unit 21L-1 performs control so that the contact lenses 1L-1 and1R-1 can operate in coordination with each other. More specifically, thecontrol unit 21L-1 performs control so that a display unit 26, which isprovided to the other contact lens 1R-1, can display an image imaged bythe imaging unit 24, for example.

Hereinabove, the specific description has been given of theconfiguration of the contact lens 1L-1 according to this embodiment.Meanwhile, as shown in FIG. 3, the contact lens 1R-1 has a control unit21R-1, the radio communication processing unit 22, the antenna 23 and afunction unit 30R-1. The function unit 30R-1 includes the display unit26.

(Display Unit 26)

In the display unit 26, multiple display elements (not shown) arearranged. Each display element is formed, for example, of a liquidcrystal display device, an organic electroluminescence (EL) displaydevice, a field emission display (FED) display device or the like. Thedisplay elements are arranged in a matrix on a curved surface (curvedsurface having an approximately spherical shape, for example)corresponding to the surface of a human eye (or an eye of a non-humananimal when the animal wears the contact lenses 1). The displayelements, each of which has a display area, may each display anindependent image, or may collectively display a single image as awhole.

The display areas are arranged so as to cover the entire area of theregion 1A (see FIG. 1) which is inside the circle 1C. Since the diameterD2 of the circle 1C is set to a value approximately equal to or largerthan the maximum diameter D1 of the pupil 3 (the maximum diameter of theinner circumferential circle 2A of the iris 2), the display areas coverthe entire surface of the pupil 3 at all times irrespective of thediameter value of the inner circumferential circle 2A of the iris 2.Accordingly, light of images on the larger number of display areasreliably forms an image on the retina of the eyeball. Note that, in thisembodiment, the diameter D2 of the circle 1C is set to a value smallerthan a diameter D3 of an outer circumferential circle 2B of the iris 2,but may be larger than the diameter D3.

In addition, the display elements are closely arranged at a pitch fineenough to allow a person to recognize a single image therefrom as awhole (so as not to cause partial lack of the image).

While displaying no image, the display unit 26 allows light from outsideto pass through, thus allowing the user to visually recognize images ofthe outside (scenes in the real world).

(Control Unit 21R-1)

The control unit 21R-1 performs control so that the display unit 26 candisplay an imaged image transmitted from the contact lens 1L-1 throughthe antenna 23 and the radio communication processing unit 22.

Hereinabove, the specific description has been given of theconfiguration of the contact lenses 1L-1 and 1R-1. The aboveconfiguration enables the contact lens 1R-1, worn on the right eye 4R,to display an image imaged by the contact lens 1L-1, worn on the lefteye 4L.

(2-1-2. Operation Processing)

Then, with reference to FIG. 4, description will be given of operationprocessing performed by the pair of contact lenses 100 according to thefirst embodiment. FIG. 4 is a sequence diagram illustrating exemplarycoordinated processing according to the first embodiment.

As shown in FIG. 4, firstly, in step S103, the sensor 27 of the contactlens 1L-1 is turned ON. Specifically, for example, upon power supply tothe contact lens 1L-1 or upon receiving a predetermined trigger signalfrom outside (from an external communication terminal, such as asmartphone or a tablet terminal, carried by the user), the sensor 27becomes powered on. Upon powered ON, the sensor 27 outputs a sensingresult to the control unit 21L-1.

Next, in step S106, the control unit 21L-1 detects the camera activationcommand based on the sensing result by the sensor 27. Specifically, forexample, when the piezoelectric sensor (example of the sensor 27) isconfigured to detect opening and closing of an eyelid contacting thecontact lens 1L-1, the control unit 21L-1 may detect, as the “cameraactivation command,” the user's action of closing the eyelid twice.

Then, in step S109, upon detecting the “camera activation command,” thecontrol unit 21L-1 activates the imaging unit 24.

Next, in step S112, the control unit 21L-1 detects the imaging command(shutter command) based on a sensing result by the sensor 27.Specifically, for example, the control unit 21L-1 detects, as the“imaging command,” the user's action of consciously closing the eyelidthat contacts the contact lens 1L-1 (of closing the eyelid for more than0.5 seconds, for example).

Then, in step S115, upon detecting the “imaging command,” the controlunit 21L-1 causes the imaging unit 24 to image a subject.

Next, in step S118, the control unit 21L-1 transmits the image imaged bythe imaging unit 24 to the imaging command received from the contactlens 1R-1 through the antenna 23 and the radio communication processingunit 22.

Then, in step S121, upon receiving the imaged image from the contactlens 1L-1, the control unit 21R-1 of the contact lens 1R-1 turns ON thedisplay unit 26.

Then, in step S124, the control unit 21R-1 performs control so that thedisplay unit 26 can display the imaged image received from the contactlens 1L-1. This enables the user to view, on the contact lens 1R-1, theimage imaged by the other contact lens 1L-1.

Then, in step S127, the control unit 21R-1 turns OFF the display unit26. The timing to turn OFF the display unit 26 may be either a timingwhen a predetermined time passes after the imaged image is displayedthereon or a timing when a “display unit end command” is detected. The“display unit end command” may be either transmitted from the contactlens 1L-1 or, if the sensor 27 is provided also to the contact lens1R-1, detected based on a sensing result by the sensor 27.

Meanwhile, in step S130, the control unit 21L-1 of the contact lens 1L-1detects the “camera end command” based on a sensing result by the sensor27 therein. Specifically, for example, the control unit 21L-1 detects,as the “camera end command,” the user's action of consciously closingthe eyelid that contacts the contact lens 1L-1 three times.

Thereafter, in step S133, upon detecting the “camera end command,” thecontrol unit 21L-1 turns OFF the imaging unit 24.

Hereinabove, the specific description has been given of the coordinatedoperation according to the first embodiment. This embodiment enables thepair of contact lenses 100 to perform the coordinated operation of theimaging function and the display function.

As shown in FIG. 5, the contact lens 1R-2 has a control unit 21R-2, theradio communication processing unit 22, the antenna 23 and a functionunit 30R-2. The function unit 30R-2 includes an illumination unit 28.

(Illumination Unit 28)

The illumination unit 28, which is provided in the region 1B of the lenspart 10, is formed of a light emitting unit and a light emission circuitconfigured to cause the light emitting unit to emit light. Theillumination unit 28 performs a light emitting operation in accordancewith control by the control unit 21R-2. Since the light emitting unit isattached so as to illuminate the front of the user who wearing thecontact lens 1R-2 on the eyeball 4A, the illumination unit 28 canilluminate in the imaging direction (which is approximately the same asthe user's eyesight direction) of the imaging unit 24 of the contactlens 1L-2.

(Control Unit 21R-2)

The control unit 21R-2 controls the ON and OFF of the illumination unit28 in accordance with a command transmitted from the contact lens 1L-2through the antenna 23 and the radio communication processing unit 22.

Next, in step S158, upon receiving the turn ON illumination command fromthe contact lens 1L-2, the control unit 21R-2 of the contact lens 1R-2performs control to turn ON the illumination unit 28.

Then, in step S161, while the illumination unit 28 of the contact lens1R-2 is turned ON, a control unit 21L-2 of the contact lens 1L-2 causesthe imaging unit 24 to image a subject. This enables the coordinatedoperation in which the contact lens 1L-2 performs imaging while theother contact lens 1R-2 illuminates in the imaging direction. The imageimaged by the imaging unit 24 may be either stored in a memory areaincluded in the control unit 21L-2, or transmitted to an externalcommunication terminal (a smartphone or the like carried by the user)through the antenna 23 and the radio communication processing unit 22.

Next, in step S164, the control unit 21L-2 detects the “camera endcommand” based on a sensing result by the sensor 27. Specifically, forexample, the control unit 21L-2 detects, as the “camera end command,”the user's action of consciously closing the eyelid that contacts thecontact lens 1L-2 three times.

Then, in step S167, upon detecting the “camera end command,” the controlunit 21L-2 transmits a turn OFF illumination command to the contact lens1R-2 through the antenna 23 and the radio communication processing unit22.

Then, in step S170, the control unit 21R-2 of the contact lens 1R-2performs control to turn OFF the illumination unit 28 in accordance withthe turn OFF illumination command received from the contact lens 1L-2.

Thereafter, in step S173, upon detecting the “camera end command,” thecontrol unit 21L-2 of the contact lens 1L-2 turns OFF the imaging unit24.

Hereinabove, the specific description has been given of the coordinatedoperation according to the second embodiment. This embodiment enablesthe pair of contact lenses 100 to perform the coordinated operation ofthe imaging function and the illumination function.

«3. Conclusion»

As described above, the contact lens 1R and the contact lens 1Lconstituting the pair of contact lenses 100 according to any of thepresent embodiments have mutually different functions, and performcoordinated operation of these functions. Thereby, the contact lensesare significantly improved in convenience.

The preferred embodiments of the present disclosure have been describedabove with reference to the accompanying drawings, whilst the presentdisclosure is not limited to the above examples, of course. A personskilled in the art may find various alterations and modifications withinthe scope of the appended claims, and it should be understood that theywill naturally come under the technical scope of the present disclosure.

For example, there may be developed a computer program for causing thehardware, such as a CPU, ROM and RAM, embedded in the circuit unit 20 ofeach of the contact lenses 1 to achieve the functions of the controlunit 21 of the contact lens 1. In addition, there may be provided acomputer-readable storage medium storing therein the computer program.

In each of the above embodiments, it has been described that thecoordinated operation is performed while the contact lenses 1R and 1Lare worn on the respective eyes. However, exception handling processingmay be executed upon removal of any one of the contact lenses 100 pairedtogether. For example, upon failing to receive any reply from any one ofthe contact lenses, the other contact lens may perform control to stopthe processing of transmitting an imaged image, a command or power.

The contact lenses 1 according to any of the present embodiments may beapplied to any types of widely-known soft or hard contact lenses havingdifferent lens properties and lens diameters.

Moreover, in the above flowcharts, it does not matter if the processingof transmitting each command does not end until the command completionnotification is received from the command's destination. For example,the “processing of transmitting the turn ON illumination command” shownin S155 in FIG. 6 ends upon receipt of a command completion notification(turn ON illumination notification) from the contact lens 1R-2, and thenthe “imaging processing” shown in S161 is performed.
